1) I second the notion that more rope schemes should be added, though exact rules for implementation would need discussion (e.g., bo3 for ZaR Shopper?)
It would be cool if people that traditionally played a lot of classic got into TFL because of more rope schemes, since it's a really diverse and fun league.
2) I also like idea of getting rid of least played schemes; kinda like relegation in professional (european) football leagues.
3) Dislike Pizza's idea of full random, since you would end up playing schemes you don't like and won't HF.
